8 mnth completely off solids... Should I worry???

Hello!
Having been enjoying food and weaning well, my 8mnth DD has stopped eating solids completely. She's still b/f fine but cries when I try and give her solids. It's stuff she was eating happily so I know she likes it. She's teething (first tooth arrived last week) - could it be that? It's been a week already so I can't help worrying!
Tell me it's normal!

agree with all strategies so far - milk is the most important thing - but you can also try leaving scraps of finger food casually on the highchair tray so if she fancies them she can eat them but leave them if not.
